Lower perf with TB5 vs TB4
Title. I'm running a MS-02 Ultra 235HX with a NIMO 7600M XT eGPU. I get 23k in Firestrike on the TB4 port, and barely 19k on the TB5 ports (both of em). 3Dmark bandwidth test shows 5.8 Gb/s with TB5 and 3.0 Gb/s with TB4. My 226v Lunar Lake laptop actually gets 3.2-3.4gb/s on its TB4 and gets 24-25k in Firestrike to match it. So I know the 3dmark results are accurate and I've checked the GPUs boosting to 120w.
(Scores talked about are Graphics score specifically, ofc)
Anyone got any idea what's going on? I'm about to just say fuck it and blow some money on a OCULink PCIe card and nice cable. I don't think buying another TB5 cable would be worth it, they're like $80.
